摘要
利用光纤传输快速、可靠性高的特点,将支线设备故障时的判别信号传送到电源侧,再通过简单的逻辑判断实现保护功能的开放和闭锁,以保证区内故障时保护动作的选择性,从而解决配网保护选择性差的难题,提高配网供电的可靠性.
By making use of the characteristics of optical fiber's fast and reliable transmission, we transmit the identification signal to the power supply side when the feeder equipment fails and then through simple logical judgment, we can achieve the open and latch up protection function so as to en- sure the selectivity of the protection actions when internal failure happens, thus solving the problem in the poor selectivity of distribution network protection and improving the reliability of distribution net- work power supply.
